In a state of grief or sorrow; grieving or troubled, archaic usage.
From Old English a- (in or at) combined with grief (from Old French grief, from Latin gravis meaning heavy). The prefix a- marked states or conditions.
Agrief is an almost-dead English word that shows how old English used the prefix 'a-' to mark states (like 'ablaze' or 'asleep')—you don't hear it anymore because modern English dropped this grammatical pattern, but its absence leaves us with fewer poetic ways to describe emotional conditions.
